WebApr 9, 2024 · There are inherently irreversible processes irrespective of its velocity, for example, the hysteretic behavior of a ferromagnet is always dissipative and thus irreversible at any rate of the process. Similarly, the plastic deformation of a metal bar is always dissipative and irreversible. WebApr 12, 2024 · A reversible process is a quasi-static process. Application-Based Questions 1. Let's take an example of the daily based activity, of pumping air inside the tire of a bicycle using a hand pump. Here, we would consider air inside the pump is a thermodynamic system having Volume V at an atmospheric pressure P, and the room temperature, 30°C.
Irreversible Process - an overview ScienceDirect Topics
WebMelting or freezing of ice in water is an example of a realistic process that is nearly reversible. Additionally, the system must be in (quasistatic) equilibrium with the surroundings at all time, and there must be no dissipative effects, such as friction, for a process to be considered reversible.

WebExamples of irreversible processes include the following: (a) a chemical reaction in which a precipitate forms; (b) the explosive combination of hydrogen and oxygen to form water; (c) the diffusion of perfume vapor into air. Irreversible processes occur spontaneously within a system that is not in thermodynamic equilibrium. WebApr 12, 2024 · A reversible process is the process where it never occurs; on the contrary the irreversible process is the one which can be said to be the natural process and cannot be reversed.
